Problems solved by technology

However, both electronic sensors and optical fiber sensors need to be connected with wires or optical fibers to obtain energy or transmit signals. When there are many measuring points, wiring is difficult. In addition, in the event of a disaster, the lines are easily damaged, resulting in sensor failure.

Abstract

The invention relates to a passive wireless inclination monitoring device based on a patch antenna. The device comprises a label and a reader, the label comprises a fixed assembly and a movable assembly, the movable assembly comprises a first dielectric plate and a first patch arranged on the first dielectric plate, and the fixed assembly comprises a second patch, a second dielectric plate, a microstrip feeder line, a chip and a ground plane. The second patch, the microstrip feeder line and the chip are sequentially connected and arranged on one side surface of the second dielectric plate, the ground plane is arranged on the other side surface of the second dielectric plate, the first patch and the second patch are in a sector ring shape, and the second patch and the second dielectric plate are concentrically arranged face to face. The first dielectric plate is rotatably arranged on the second dielectric plate around the circle center of the second patch, and the label is vertically arranged on a measured object. Compared with the prior art, the wireless passive detection is realized, the structure is simple, the installation is simple and convenient, the external interference is small, the service life is long, the cost is low, and the positioning is accurate.

Description

technical field [0001] The invention relates to the field of structural health monitoring, in particular to a passive wireless tilt monitoring device based on a patch antenna. Background technique [0002] In the field of structural health monitoring, the inclination angle is an important parameter for building health monitoring. The current common tilt sensors can be divided into mechanical, electronic and optical fiber. [0003] Mechanical tilt sensors have the advantages of easy design, low cost, reliable performance, and intuitive measurement data. However, mechanical tilt sensors have a limited range of use, small measurement ranges, and difficulty in connecting to the network, making it difficult to achieve real-time monitoring. Electronic sensors and fiber optic sensors have the advantages of high integration, high precision and easy connection to the network, enabling remote and real-time monitoring of building tilt. However, both electronic sensors and optical fib...
